convert metres to decimal deg

[Ed McNierney]

Raghu -

You can't.  The relationship is non-linear, and depends on the location
of the point.  MapServer can easily reproject your data layers
dynamically for you so you can combine those data sets in a single map.

Subject: [UMN_MAPSERVER-USERS] convert metres to decimal deg

Hi,
        I have a few raster datasets in Geographic coordinate system
(extent units in decimal deg), and a few datasets in Proj Coordinate
system (extent units in meters)

Are there any resources/formulae to convert meters to corresponding
decimal degrees, without changing the projection type?

Thanks,
Raghu
